Mach Transducer Selector
Normal operation is selection in the pitot/static position.
The mach transducer is operated in the pitot-static position and is used to cross check for errors from the micro air data computer system. This is accomplished by providing dissimilar source for mach number, airspeed and altitude inputs.
Stick Shaker Actuator
A stick shaker (mechanical vibratory device) actuator is located on each control column and provides tactile sensing, simulating airplane buffeting.

STALL PROTECTION COMPONENTS (CONT'D)
Stall Pusher
If the angle of attack increases to a point where the airplane’s stall margin is too small, the SPC will command a push of both control wheels. This is accomplished using a motor assembly which will drive the forward left elevator quadrant. The right control wheel will receive its input to push through the coupled automatic pitch disconnect mechanism.
The pitch disconnect mechanism has a function to engage a solenoid piston to prevent elevator split during push.
The pitch disconnect solenoid is controlled by the SPC and when operated, prevents the automatic pitch disconnect mechanism from activating when push is commanded by the SPC.
When the AOA approaches pusher firing angle (1. degrees before push occurs) the pitch disconnect locking mechanism is activated. When the push is cancelled, the solenoid for the pitch disconnect locking mechanism is deactivated.

STALL PROTECTION COMPONENTS (CONT'D)
Stall Protection Disconnect Buttons
The stall protection disconnect buttons are located on the pilot and co-pilot control column. These switches also provide a disconnect command to the autopilot and pitch trim functions.
NOTE
A “STALL PROTECT FAIL”caution message will be displayed if the disconnect button is held for longer than 12 seconds.
This stick pusher may be stopped by pressing and holding the autopilot/stick pusher disconnect (AP/SP DISC) switch. This will remove power to the actuator as long as either switch is depressed. The stick pusher is capable of operating immediately once the autopilot/stck pusher disconnect switch is released, and a stall push is requested by the computer.
NOTE
The remaining stall warning functions are available with the disconnect button held. All other SPS functions operate normally.

The stick pusher may be stopped by pressing and holding the autopilot/stick pusher disconnect (AP/SP DISC) switch.
The SPC will remove power to the actuator as long as either switch is activated and the push will be cancelled. The stck pusher is capable of operating immediately once the AP/SP DISC switch is released and a stall push is requested by the computer.
